'10 all whom it may comm-n:

F. MoFnnnY,

Be it known that I, Ronnnn a citizen of the United States, residingat Beverly, in "the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Apparatus for Making Boots and Shoes, of which the followingdbscription, in connection with the accompanying drawings, isa specification, like 'referencecharacters on the drawings indicating like parts in the several figures.

This invention relates to apparatus for working an upper orer a last, certain features of the invention being directed particularly to grippers, their mode of operation, and actuating mechanism therefor.

A very important feature of this invention consists in grippers which are adapted to engage the upper about the end portion ofa shoe and are formed in relatively movable, preferably curved sections arranged to I contour of the end By this arrangement the same grippers may be employed with lasts of difierent widths and shapes and will conform to the shape or the particular last being .used.

A further adapt themselves to the feature of'the invention consists in means for returning to a uniform rela-- tive position gripper sections which have been relatively shifted to adapt them to the shape of the shoe last operated upon.

In accordance with the preferred arrangementwhich involves still a further feature of this invention the gripper sections are returned after each pulling operation to a. starting position or relation in which they are or may be'spread apart to receive the upper of a last of maximum size and are caused to pull the upper initially in a direction outwardly from the side faces of the last. An advantage of this feature of the invention is to be found in the fact that the upper is initially .pulled over the top face of the last with a minimum of frictionalresistance by contact with the side faces of the last. By this ineans the upper is first straightened over the top of the last, removing all wrinkles and fullness and then is gradually wrapped about the sides of the last. and as herein shown. finally drawn inwardly over the edge of thelast and .thcn laid down upon the. last bottom. After the upper is released and While the grippers a re being lowered to gripping position for the next shoe the sections 5 5 are automatically spread apart. Provision is made for adjusting the spreading means to accommo d ate the. range of sizes of lasts that are being used. A desirable characteristic of the illustrated construction is that receive right or left lasts that have more swing or fullness on the outer side than on the inner side. lit is customary to last a series of rights and then a series of lefts, as for example the rights and then the lefts of .a case of shoes, and the positioning means can be made to retain the grippers automatically to position for receiving such right lasts and then when the right shoes have been treated, can be adjusted to return the the left shoes.

.. In addition to the provisions above de- 'scribed for relatively shifting or adjusting the sections of thegrippers, or relatively changing their normal positions, a further feature of this invention contemplates pro-r vision for adjusting transversely of the last the grippers that engage the upper at the end and sides of copending application Serial No. 372,055 to adjust asingle toe gripper transversely of the last but it is new,'as I am advised, to

adjust widthwlse of a last gripping devices as well line of the forward portion extends obliquely to the median line of the rear portion. \Vhen the heel portions of such lasts are supported in substantially uniform position the toe end of a right last is located at the right of the central position of the grippers and the toe end of a left last at the left side. of that position and the transverse adjustment of the" forepart grippers is of gibvious importance in order to obtain a suitable square pulling When the widthwise adjustment is used with the relative adjustment of the curved gripper sections, as 'is herein shown, the grip- Patented Apr. is, 19115.

grippers thereafter to position for receiving 75 I the end of the shoe. It has' heretofore been proposed as explained in my as of the upper.

'. the toe end and pers can be positioned to receive a crooked ast having excess of swing on its outer side in approximately the same relation as a straight last is received. 7

In accordance with a further feature of this invention means is provided for simultareously adjusting the grippers for swing an illustratedhas also out adjustment transversely and rotatively.

Another feature of this invention consists in thecombination with grippers that have v I jaws curvedor arranged to present substantially continuous gripping faces for engagmg an upper at the sides and end of the toe portion of a shoe, of means for actuating the grippers upwardly and forwardly with relatlon to an inverted last. By this combination the grippers are caused to apply to the full width of the forepart of the upper a forward strain which draws the entire upper toward the toe of the last prior to wrapping the upper over the end of the last.

further very important feature of this invention consists in means for actuating gripping devices which engage the upper at the opposite sides of the toe portion of the shoe. These devices are herein shown as the sectional curved grippers before referred to which are formed to embrace the toe portion of the shoe and to receive and pull the upper throughout the breadth of its forward portion, at the sides as well as at the end of the too but no limitation not clearly expressed in the claims is to be implied by theillustration 'of this particular embodiment of the invention. In accordance with this feature of the invention as herein applied the portions of the gripers that pull the upper at the sides of the s 0e are lifted relatively to the portion which pulls at the toe end of the shoe. This relative movement occurs near the end of the pulling operation all'tLby thus actuatin the rippers the up er is first stretched forwardly and .upwar 13] over the toe end and then the portion engagedby the rear parts of the grippers receives an additional pull,

that draws it snugly to the last. If the gr ppers present substantially continuousgrippmg edgesas herein shown the relative uplift o their rear ends affects an additional pull which is fmaximumextent at the rear ends of the jaws and gradually decreases toward the toe. This additional pul l is of special value in conforming an upper to a last, such as many in use at the present time, which is high or thick over the toe and relatively lower from the toe to and over the ball. It is particularly difficult to shape the upperover such a last but this movement of the grippers produces a tightening of the upper over the rear sloping face of the high toe that is very effective. -In the cro'okedness of the last. The means 'b provision for independof the grippers sections cline at the back of the toe and -ch1ne. As explained in Letters mma'king sho s on crooked lasts,

preferred embodiment of this invention the whole forepart gripper is actuated forwardly during its up ifting increment and particularly during the first part of that movement. This effects a forward pulling of the entire upper throughout its breadth as distinguished from a pull that is exerted y a narrow upwardly-drawing toe gripper mainly along the middle of the upper, and thus more thoroughly takes the lengthwise stretch from the upper and also draws it over the toe with a minimum of binding against the side faces of the last. Another advantage incident to this forward pull is that the upper is drawn downwardly along the inclined top face of the last. This forward pulling of the upper preferably begins while the upper is held away' from the side faces of the last at which time the up er may be pulled over the top of the last with the least frictional resistance. This forward movement of the grippers is effected as shown by a cam over which the gripper bar engages as the bar is lifted. During this lifting the upper end of the bar engages an incline by which that end is moved forwardly, the bar fulcruming on the cam and the rear or heel end of the gripper jaws being relatively lifted while the jaws may swing backwardly somewhat, but this backward movement is partially or wholly offset by the inclination of the said can-1. By this movement the upper is drawn into the inis wrapped over the toe end while under tension for conforming it to the contour of the last.

In the form of grippers herein shown which include sectional curved jaws the work of centering the last laterally is very much facilitated. By the use of the device for shifting the grippers laterally, as herein explained, the grippers may be adjusted to position right and left crooked lasts in proper lateral-relation to the side grippers and the other instriunentalities of the ma- Patent of the United States No. 1,030,264, granted. on my prior application, Serial No. 540,221, filed Jan. 26, 1910, the/side grippers of the machine in which this invention is shown as applied are adapted to be employed as gages or tip seam position indicating means by the aid of which the operator can insert the upper with the tip seam in predetern'iincd relation to the machine. By the use of the last end abutment additional. accuracy is secured as to the length of the toe ti 7 from the end of the last to the tip seam. 'lso by the use of a last end abutment which also centers the last. laterally there is greater surety of obtaining a correct angular relaor as it is called, a

straight tip seam. This is particularly the case when, a means 1s This offsets partially or wholly the toe end andare sii'nultaneously the upperover the employed'for adjusting laterally the last end abutment constituted by the toe gripper to adapt it for the right and the left last.

In the machine herein shown as embody ing this invention wipers are employed to wipe into lasted position about the forepart of the last the upper whicl. has been pulled by the described grippers.

These wipers are mounted by means which includes a novel feature of he present invention to adjust themselves to a crooked last by movements similar to those described for the g ippers. These wipers are actuated luu'ii' ardly from closed inwardly from the sides of the shoe to force position. The backward movement of the wipers has an obvious tendency to force backwardly along the edge of the last the upper at the sides of the shoe. This b tch- Ward pressure on the upper has a well recognized tendency to produce fullness, some-- times resulting in a wrinkle in the upper, at the ends of the wipers. it is a feature of this invention that the forward movement of the ,grippers'which engage the upper atthe sides as ,well as at the toe end stretches the entire forward portion of the upper toeward, including the marginal portion at the sides of the shoe as well as at the toe end.

the backward push of the wipers at the sides of the shoe and prevents the formation of the objectionable fullness which has heretofore been dillicult to avoid. Preferably the grippers hold the upper under forward tension while the wipers are acting thereby still further counteracting the backward push of the wipers.

The patentable novelty herein disclosed in methods of making shoes and which may advan-J which relates to improvements tageously be practised by. the aid of the described mechanism, although it may also-be employed'with other apparatus or in making shoes wholly or claimed in this application but constitutes the subject-matter of a divisional application Serial No. 599,337.

These and other features of this invention which it is my intention to protect will be more'fully explained in connection with the descriptior of the mechanism in' which I have illustrated the invention? ias emb odied and will then. be restated in thclaims.

Fig. 4: is a perspective view of the grippers showing them in a position occupied after they have gripped and pulled the upper.

The machine which except for ping and pulling means may be the same as that shown in said copending application comprises means for resting a shoe including a bottom rest '2 and a heel rest 4. The mechanism for pulling the upper is actuated from ber 12 of the gripper lever. This bar has Y two depending studs or rods 16, eachof which slides in a sleeve which forms the upper end of a carrier 18. The gripping members, which comprise pivoted jaws 19 and relatively tixed jaws 20, are formed in sections, one section of the fixed jaw and one section of the pivoted jaw being supported by each of the carriers 18. The construction of a carrier. and its jaws is shown in the sectional view, Fig. 3, wherein it will lie-seen that the rigid memberQO is immov- I ably fixed to the carrier, while the movable member 19 is pivotedto the carrier and has a 'tail piece extending upwardly between guiding surfaces 'on a plunger 25. The plungeris fastened by the pin 26 to the bar 15 and-the carrier 184s yieldingly pressed downwardly with relation to the bar and the plunger by a spring 28. This arrangemerit-causes the carrier with its jaws to be moved by the spring dO'WIIWztIdly with relation to the contacting faces on the head of the plunger, whereby the. pivoted jawis swung toward thehxed aw for closing the 'lVhcn' the, lever l0, 1.2 is moved grippers. in the direction for uplifting the grippers the movement is transmitted through the bar 15 and the plunger 25 for n'iaintaining thc grippers closed.

7 In. order to open the grippers the carrier 1.8 is n' ovidod with shoulilers 30 (see Fig. i) adapted to engage seats Ul. abutments which are rigidly supported and hold the carrier with relation to the descending bar and the plunger, thus forcing the contacting faces of the plunger dtnvnwardly along the tail piece of the pivoted jawand rocking the jaw into the position shown in Fig. 2. The gripper carriers can-be raised manually, with the grip tance for swinging member 27. pivoted to the leversection 12 and having toothed engagement with a hand lever 29. The jaws are curved and preferably have substantially continuous gripping faces to receive the upper on the opposite sides and the end of the toe 0r forward portion of the shoe, as shown best in Figs. 4 and 5. 'As herein shown, the rear or heel portions of the jaws extend backwardly from the carrier a considerable disengaging the upper along the sides of the shoe.

The arrangement by which the sections of' the aws at opposite sides of the middle of the shoe are separately mounted upon the rotatable carriers 18 permits the jaws to be adjusted or spread for shoes of different sizes. Preferably the jaws will be formed and normally positioned in a larger curve or a curveot longer radius than the curvature of the end portion of the last. For positioning the sections of the jaws each shoulder is arranged to engage a positioning device having inclined walls between which tl e shoulder becomes seated and by which the carrier is angularly adjusted onits stem 16 when the grippers are depressed and opened for receiving the stock. The positioning devices are supported on plates 36 for angular adjustment and to this end said devices have curved slots through which extend pins from the plates 36. The pins carry clamping or fastening means 37 which may be set up for holding the positioning devices in adjusted position. It will be observed that the devices for the two sides of the grippers are-independ ently adjustable so that they may be relatively positioned to adapt the sections of the-grippers to lasts having more-swing on the outer side than on,thc inner side. The described positioning means determines the annular relation of the sections of the grippol-s when in grip 'iing position and their relation during the initial portion of the pulling movement- As the pulling movement progresses, however, the shoulders 30 rise out of contact with the positioning devices and the sections of the grippers are then free to position themselves according tothe edge contour of the forward portion of the last. A spring 48 mounted on a rod extending between. ears on the outer edges holdingthesections normally spread apart with a.yielding; .fonce; By thisspring the sectionslof' the grippers are yieldingly restrainedand steadied in swinging together 3 dur ng the npperistretehing operation. The

more important function of this spring,

- Most of the lasts in use are be employed for.

however, is to separate or swing outwardly the sections of the jaws after the jaws havebeen closed inwardly during the action of the wipers, as will be later described.

The plates 36 through which-the carriers 18 are guided and upon which the positioning devices 35 are adjustably supported are themselves mounted for adjustment trans rersely of the machine last. To this end said with a rack bar 45 which is engaged by a segment on a lever 46 having a spring looking pin for engaging a ratchet to hold the rack bar in adjusted position. The connection between the rack bar and the plates 36 is an indirect one formed by the guide bars 49 in which the plates 36 are movable forwardly and backwardly or length- Wise of the last.

Fig. 8 shows meanswhich may be used with the parts shown in Figs. l-and 4 for simultaneously adjusting angularly the positioning devices 35 for the two gripper plates are connected sections and, inasmuch as the shoulders 30 on the gripper section carriers rest in the devices 35 the illustrated construction ovides means for adjusting the curved ore part grippers angularly about an axis in the ine of their pulling movement. As shown in said figure, the plates 36 have toothed collars surrounding the gripper carriers 18 and a lever 50 is pivoted at 51 onthe plate 36. Segments'52 are mounted on the same pivot and are independently and adjustably connected by readily accessible screws 53 to the adjacent short arm of the lever. The long arm ofthe where the operator can readily engage it for adjusting the positioning devices andtherefore the gripper sections together angularly, it being understood that the clamps 37 are loosened at such times. A spring pin 54 engages a fixed roughened plate 55 to retain the lever in its adjusted position. This plate 55 is shown as having ears 56 which receive adjustable stop screws 57. These screwsmay serve to limit the throw of the lever for the particular style of lasts being operated upon which have excess of swing on their outer sides. The lever would be thrown against one stop as shown to adjust the grippers angularly for a right last and against the other stop for a left last. crooked as well as having excess of swing on the outer sides and the arrangcment'shown' in Fig. 8 provides for simultaneously adjusting the grippers transversely of the last and also angularly. The lever 50 ispivoted to the plate 36, while the plate 55 is stationary so that whelr the lever 46 is manipulated the lever or widthwise of the lever extends forwardly right-hand end gular direction, 'theoneat the right having moved inwardly and the one at the left having tui ned outwardly on the outer side er:

ihe dotted lines show the position which a similar left last will occupy and it will be readily understood that a movement of the slide L5 toward the left will afie d) theap propriate adj ust for the greater swing that last. ,It willbe observed that trans,- verse adjustment alone takes place during the first part of the movement of the adjusting slide 45 and that theang ular or turning adjustment of' the grippers occurs.

during the last part of that movement of the slide. Alimited lateral adjustment to either side of the median line of themachine can,

By adjusting the stops 5'? the amount of angular adjustment of the grippers automatically obtained during the lateral adjustment can. be variedor they can be retracted to render them inoperative and angular. adji f tme nti wheii required be obtained by separa "fii ovement of the lever 50. i I

The I gripper bar 15 is provided on its rear face with a cam surface 60, or as shown in Fig. 4. with apair of cam surfaces 60, adapted to engage a roller 62 which is maintained in a fixed position during the uplifting movementof the grippers and serves to swing the gripper bar wardly. By this means the upper at the opposite sides and the end of the forward portion of the-shoe is strained forwardly while being pulled upwardly. The member 12 of the gripper vided with depending guideways 7 2, the adjacent faces of which are inclined upwardly {and forwardly, as shown in Fig.1. The

frame of the machine supports a roll having astud- 74 with which these inclined faces are adapted to engage as the guidin g pulling the upper. This on gagement compels the member-l2 of the le- 4 the gripper bar forwar inclines:72 on the ver to slide forwardly with relation to the member 10-, thus carrying the upper end of dly and causing that bar to fulcrum or rock about its point of engagenient} with-the combined roller 62.

caused by the cam faces andth e inclines are represented diagrammatically in Fig. 6.

It willbe observed tially neutralizes the tendency of the incline 72 to move the gripper jaws backwardly while it does not lessen the upward movement or liftingof the heels of the jaws. The machine comprises means fully explained in said co-pending application and in-United States Letters Patent-663,777 for effecting or permitting relative adjustment of the upper and last after the up or has been pulled and while it is held un er tension for the purpose "of straightening and .30

accurately positioning the upper in pulled over position upon the last. The construc-. tion of this mechanism formsno part of the present-invention and is, therefore, not here-"described.

. The lasting devices for forcing the pulled-over upperinto lasted position comprise the side wiper plates and the connecting wiper guidewa'y or groove free sliding movement transversely of the that the cam face 60 parplate 82 mounted in a curved I 83 in the carrier 84 for last. The side wipers are connected by links 85 and an equalizing bar 86-with a rack bar 88 arranged to be actuated'by a shaft having a hand lever90, as shown in Figs. 1 and 5. A spring 92 forms a yielding element between the connecting plate 82 and the rack I bar 88: The arrangement of the'wipers and their actuating mechanism ermits the wipers to move transversely o the shoe in a curved path to adjust themselves as indi cated in Fig. 9 to the position and the shape of the last and causes the wipers to be moved lengthwise of the last and simultaneously the bottom of the last from the opposite sides as the hand lever 90 is turned. During this'mov'ement of the wipers the grippers may be forced backwardly moreor less and will also close inwardly overfthe shoe bottom, the roller- 62 controlling the backward movement of the grippers and preferably causing them to maintain a forward tension on the marginal portion of the upper.

In the'use of the machine a shoe will be positioned against the rests 2 and 4 and the marginal portion of the upper inserted between the gripper jaws whichare automatically depressed and-opened at the end of each operation. I The form and position of the sections of the fore p'art them to receive the forward portion of. the upper about the curved en ofthe last and the continuous gripping faces hold the upper without permitting any wrinkles to form in it. When the machine is started the grippers are closed and uplifted, the

fore part grippers gripping and pulling the entire toe portion of the upper at' both sides substantially as far back as the usual lasting wiper" lates reach as well as at grippers adapts the the end" of the last,

' so engaged the upper The positioning devices 35 spre'ad the-sections of'the'grippers apart and insure an. initial pulling of the upper obliquely away from the sides of the last whereby the upper is drawn over the top face of the last. As the stops 30 rise from their seats in the positioning devices the carriers 18 are of the jaws to the width and shape of the last and in this movement the upper is wrapped or drawn up against the side faces of the last. During the rise of the causing the sides as well as the toe end of the upper to be strained lengthwise ofthe last. The upper and particularly the marginal; portion of the upper is preferably held under such lengthwise strain or tension during tlie subsequent operations on the shoe. In the latter part of the rise of the grippers the inclines 72 become operative for moving the upper end of the gripper bar forwardly and lifting the heel ends of the gripper jaws. This movement of the heel ends of the the sides of the toe with relation to the upper at the end of the toe. This movement is of particular importance in drawing the upper snugly down to the Wood of the last over the sides formed, as is common at the present day, with a nub or high place over the toe, as indicated in Fig. 6,the relative upward movement of the heel ends of the jaws draws the upper down upon the rear. incline of this high place, at a portion of the shoe which has heretofore been difficult to shape snugly. The machine automatically comes to rest with theupper under tension to permit the operator to inspect the shoe and adjust the upper to the last relatively. If at this time it is found that the fore part gripper has not as to pull it correctly upon the particular last in the machine the gripper may be shifted or moved trans versely of the last by means of the rack bar 45 and the lever. This adjustment may be employed for effecting a movement of the upper transversely across the last especially the part of the upper at the sides of the toe engaged by the rear portions of the jaws. If necdful the gripper lever which is provided with a handle on itsfront endand is yieldinglyconnected to its cam at the rear end may be depressed to slackcn the pull of the forepart grippers while this adjustment is being made or for any other purpose and in the event that the operator finds it necessary to release the toe portion of the upper the gripper jawsmay be opened and reengaged with the upper by manipulating the hand lever 29. After the upper has been ulled and such adjustments made as are permitted to swing by the. tensiop of the upper to adapt the position grippers I the cam'60 forces. the grippers forwardly,

jaws effects a final pull on the upper at of the toe and if the last is conforming the upper to the last necessary for completing the pulling-over operation the wipers are advanced for force,

must move rearwardly or lengthwise of the shoe. This movement of the side wipers backwardly in contact with the upper as they are being closed inwardly tends to push the upper backwardly at the rear ends of the wipers, but this tendency is offset or partially offset by the forward pull which has been givento the upper and preferably also by the fact that the grippers are still holdin the upper under lengthwise tension; Thus t e formation of fullness orwrinkles at the rear ends of the wipers of the endlasting mechanism is avoided.

If the lasts on which the shoes are being pulled-over and lasted have more swing or projection on the outer side of the too or fore part thanon the inner side the devices 35 may be relatively adjusted to position the If the lasts are crooked lasts having the median lines of the fore part at an an Is to the median line of the heel part the a justing means 45, 46 as well as the devices 35 may be shifted for positioning the fore l ne of the machine for pulling and lastin the left shoes and at the left hand side 0 the median line of the machine for pulling and lasting right shoes.
